Description

Technical Field

[0001] This utility model relates to the field of electrical connection device technology, specifically to a wire connector. Background Technology

[0002] In electrical applications, wire connectors are devices used to connect wires or cables. Wires are prone to aging and damage during long-term use, so they need to be maintained regularly. In the process of maintaining the circuit, it is necessary to first use wire connectors to disconnect the power to the target circuit or short-circuit it.

[0003] Existing wire connectors, such as disconnect switches, typically only have a single on / off function. In scenarios such as circuit testing and fault simulation, when a temporary short circuit needs to be created, operators must manually connect the wires using external connections. Since circuits generally require multiple tests after installation, this necessitates multiple manual connection steps, resulting in inconvenience and significant safety hazards.

The housing is provided with a bus socket and a parallel mechanism for cooperating with the parallel switch assembly. The end of the parallel mechanism away from the housing is connected to the wire via an insulating seat installed inside the insulating housing. The cover is provided with a wire fixing mechanism for cooperating with the insulating seat to fix the wire to the parallel mechanism.

[0009] Preferably, the parallel switch assembly includes a sleeve disposed inside an insulating housing, a pressure seat slidably sleeved on the sleeve, and springs disposed inside the pressure seat and the sleeve. A pressure post for penetrating the cover is disposed at the end of the pressure seat away from the sleeve, and a pressure control button is disposed at its end. A fan-shaped buckle is provided on the outer peripheral wall of the pressure base, and a contact piece is embedded in the fan-shaped buckle.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-8A wire connector includes: an insulating housing 1 for accommodating a wiring structure, a cover 2 sealed on the insulating housing 1, a parallel switch assembly 3 housed inside the insulating housing 1, and a structure at one end of the parallel switch assembly 3 passing through the cover 2 and located outside the insulating housing 1. The middle part of the insulating housing 1 has a housing 7 for accommodating the parallel switch assembly 3. The housing 7 is provided with a bus seat 6 and a parallel mechanism 8 for cooperating with the parallel switch assembly 3. The end of the parallel mechanism 8 away from the housing 7 is connected to the wire via an insulating seat 4 installed inside the insulating housing 1. The cover 2 is provided with a wire fixing mechanism 5 for cooperating with the insulating seat 4 to fix the wire to the parallel mechanism 8.

[0019] The insulating base 4 has a frame for cooperating with the wire fixing mechanism 5. The end of the insulating shell 1 has a hole for the insertion of external wires, and the position of the hole in the insulating shell 1 corresponds to the position of the frame on the insulating base 4. After one end of the target wire is inserted into the hole in the insulating shell 1, the insertion of the wire can be directly observed through the observation window 22 on the cover 2. This ensures that the connection is tight when the wire fixing mechanism 5 is turned, and avoids misalignment, poor contact, or even detachment.

[0020] The wire fixing mechanism 5 includes a pressure plate 51 slidably disposed within the frame of the insulating base 4. An inner threaded sleeve 52 is integrally formed on the pressure plate 51 for penetrating the upper frame of the insulating base 4. A lead screw 53 is provided on the internal thread of the inner threaded sleeve 52. One end of the lead screw 53 away from the inner threaded sleeve 52 passes through the cover 2 and is fitted with a knob 54. A limiting plate 55 for rotating with the cover 2 is sleeved on the lead screw 53. By setting up the wire fixing mechanism 5 to fix the target wire, compared with the common situation of using a screwdriver to fix the wire, it ensures that the wire can be easily inserted and fixed, while avoiding electric shock incidents caused by the exposed structure of the screwdriver, thus improving the safety when connecting the wire.

[0021] The cover 2 includes a cover frame 21 for mounting on the insulating shell 1. An observation window 22 communicating with the interior of the insulating shell 1 is formed on the cover frame 21. A limiting frame 23 for the parallel switch assembly 3 to pass through is formed at the position corresponding to the parallel switch assembly 3 inside the observation window 22. All the hollow parts inside the observation window 22 are sealed with acrylic sheets. By setting the observation window 22, when the wire is connected and the parallel short circuit is started, the short circuit can be directly observed, thereby facilitating the control of the parallel state at the short circuit.

[0022] The parallel switch assembly 3 includes a sleeve 31 disposed inside the insulating housing 1. A pressure seat 33 is slidably sleeved on the sleeve 31. A spring 32 is disposed inside the pressure seat 33 and the sleeve 31. A pressure post 34 for penetrating the cover 2 is disposed at the end of the pressure seat 33 away from the sleeve 31, and a pressure control button 35 is disposed at its end. A fan-shaped latching platform 36 is provided on the outer peripheral wall of the pressure base 33. A contact piece 37 is embedded in the fan-shaped latching platform 36, and the contact pieces 37 located on both sides of the pressure base 33 are electrically connected by an embedded conductor. When a short circuit is performed, the pressure control knob 35 is pressed and rotated according to the parallel connection requirements to select the first or second layer of pressing pressure, so that the fan-shaped latching platform 36 rotates and latches between the parallel connection mechanism 8 and the bus seat 6 to achieve the parallel short circuit effect.

[0023] The parallel mechanism 8 includes a first parallel plate 81 and a second parallel plate 82 located inside the housing 7 and arranged in layers. The first parallel plate 81 and the second parallel plate 82 are both provided with second terminals 84. The insulating base 4 is provided with a second conductive piece 83 for connecting with the wire. One end of the second conductive piece 83 passes through the housing 7 and is connected to the second terminals 84 embedded in the first parallel plate 81 and the second parallel plate 82 respectively. The housing 7 and the first parallel plate 81 and the second parallel plate 82 are all made of acrylic. When the parallel switch assembly 3 is short-circuited, the parallel state can be observed and controlled automatically, improving the flexibility of the connector during use.

[0024] The first-layer parallel board 81 has three sets of second terminals 84, and the second-layer parallel board 82 has two sets of second terminals 84. The surface of the second terminals 84 is silver-plated and has a resistivity of ≤0.022Ω·mm. 2 / m; Through a layered design, when the circuit is short-circuited in parallel, the parallel relationship between the three sets of connecting wires can be combined according to the test requirements. The first layer can have three parallel connection methods, and the second layer can have one parallel connection method, achieving the effect of free test combination.

[0025] The bus connector 6 includes a first layer plate 61 and a second layer plate 62 located inside the housing 7 and arranged in layers. The first layer plate 61 and the second layer plate 62 are both provided with a first terminal 64. The first terminals 64 provided on the first layer plate 61 and the second layer plate 62 are connected to the external wires through a first conductive sheet 63 passing through the housing 7. The first terminal 64 is arc-shaped. The overall structure of the bus connector 6 is also equipped with a wire fixing mechanism 5 for fixing the wires. The arc-shaped first terminal 64 can be connected to the parallel part of the parallel mechanism 8 through the parallel switch assembly 3 to complete the short circuit, regardless of the parallel connection of the parallel mechanism 8.
